- [Instructor] Here I want to talk about how we
navigate within the graphics window.
Pan, rotate, translations, zooms,
those kinds of things using the mouse.
Now the people over at DeSo have done a wonderful job
of basically controlling your screen with the mouse.
They've really simplified it but you have
to get used to the little finger dance
to make sure you get the most out of the usage
of your mouse when you're doing your panning
and zooming and everything is based off
of the middle mouse button.
So if I come in and right now hover over
the top of a bit of geometry and just simply
click the middle mouse button or your wheel,
just by clicking on that geometry it recenters
the point of rotation to that geometry
that you've selected so now when I rotate
you'll see it rotates about that point.
Now the next question that I get is well
how did you just rotate that Steve?
And the way that works is once again
off of the middle mouse button.
So if I singularly click on something
that becomes a point of rotation.
If I click and hold the middle mouse button down
you'll see now I can pan.
In order to rotate I need to now keep
the middle mouse button held down
and click either the first or the third mouse button.
It doesn't matter at this point.
Whichever you're most comfortable with.
My personal preference is I use my middle finger,
hold down the middle mouse button
and then I use my first finger or my index finger
to hold down the first mouse button.
You can do that in reverse,
you can use the middle mouse button with your index finger
and use your middle finger to hold down
the third mouse button, it does not matter.
So long as you're holding both down
and the middle mouse button is pressed first.
Now that I have them held down I am able
to rotate the part.
Now to zoom all I have to do is release either the first
or the third mouse button.
The moment I release that I'm still holding down
the middle mouse button I'm able to zoom
in and out by moving my mouse up or down on the screen.
And that little finger dance is the most efficient,
effective way to move, pan, rotate,
translate, zoom your graphics window.
So once again if I click over a bit of geometry
you'll see that it centers the part on that point
or geometry that I clicked on with the middle mouse button.
Once again holding the middle mouse button down
and I move it, that's my pan,
middle mouse button in conjunction
with the first or third mouse button is my rotate
and continue to hold the middle mouse button down
and release the first or third mouse button
and that's your zoom.
And that's the basics of how you pan,
rotate, center, translate, zoom on the part with the mouse.
